er may operate
once to indicate the change of
sensitivity.
●If the temperature of the raindrop
sensor is 194°F (90°C) or higher,
or 5°F (-15°C) or lower, the auto-
matic operation m ay not occur. In
this case, operate the wipers in
any mode other than “AUTO”.
■If no windshield washer fluid

WARNING
■Caution regarding the use of
windshield wipers in “AUTO”
mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may oper-

empty
Do not operate the switch continu-
ally as the washer fluid pump may
overheat.
■When a nozzle becomes
blocked
In this case, contact your Toyota
dealer.
Do not try to clear it with a pin or
other object. The nozzle will be
damaged.
■To prevent 12-volt battery dis-
charge
